Situation

This vulnerability allows a local attacker with SeImpersonatePrivilege to elevate to 'NT AUTHORITY\System'. Impersonation enables the server thread to perform actions on behalf of the client, but within the limits of the client's security context.

Solution

This problem has been fixed in version 20.02.00, so any later version will not be affected.
